Both battery storage and pumped hydro energy storage have their advantages and disadvantages. While battery storage is more flexible, pumped hydro energy storage is more cost-effective and has a longer lifespan. The decision of which technology to use depends on specific needs and geographic location.
Although pumped storage is able to store large amounts of energy and is the main method of storing energy today, it has many issues. Despite the fact that it has the largest capacity of any other storage types, it is limited because the facilities can only exist in areas with a very specific topography.
This is a result of the energy lost pumping the water up into the reservoir. However, pumped storage is economical because of a net increase in revenue. This is because the electricity used to pump the water is less expensive than the electricity sold at the time of peak energy demand.
These pumped storage facilities are moderately efficient, with a round-trip efficiency of about 65-70%. The amount of energy stored depends on the mass of water pumped and the height difference between the reservoirs. Pumped storage is a dispatchable source of energy since it can be deployed whenever demand is needed.
Although the losses of the pumping process makes the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand. Pumped storage is the largest capacity form of grid energy storage now available.
Pumped storage is by far the largest-capacity form of grid energy storage available, and, as of 2020, accounts for around 95% of all active storage installations worldwide, with a total installed throughput capacity of over 181 GW and a total installed storage capacity of over 1.6 TWh.

Europe and China are leading the installation of new pumped storage capacity – fuelled by the motion of water. Batteries are now being built at grid-scale in countries including the US, Australia and Germany. Thermal energy storage is predicted to triple in size by 2030. Mechanical energy storage harnesses motion or gravity to store electricity.
